The novel cement slurry plugging fluid has the beneficial effects of higher plugging and bearing property aiming at different cracks; the plugging fluid has better plugging performance than fiber plugging cement slurry, and is more suitable for a complex underground leakage stratum; the plugging fluid has excellent plugging property, and the strength of the solidified cement is lower, so as to avoid the new borehole problem caused by difficulty in drilling and plugging after the plugging fluid is solidified; the plugging fluid is prepared without complex construction processes and parameters, so that the field operation is simple and feasible.
Description
Technical field
The present invention relates to the oil drilling field, particularly a kind of novel concrete slurry leakage-stop liquid.
Background technology
The system in Tahe Oilfield leakage stopping technology is through constantly development at present; The leak stopping of bridge slurry, squeeze method leak stopping, bridge slurry and Technologies such as the leak stopping of squeeze method liquid, fibrous cement paste leak stopping have been formed; Basically Permian system leakage problem can be solved, but the leak stopping problem of the Permian system can not be solved fully.The leak stopping of bridge slurry can tackle the part leakage that is caused by hole and crack or lose and return leakage, but this method must fully realize leakage pore size or fracture opening, could adopt the material formation bridge blinding of different shapes, size.Because to the stratum insufficient recognition of leakage takes place, institute's use bridge slurry leak stopping particle is arranged in pairs or groups entirely by rule of thumb at present, one time the leak stopping success ratio is low, follow-up cementing operation is caused have a strong impact on; Conventional grout leak stopping one-time success rate is low, and the shutoff failure is caused in the often whole slits, stratum that get into of the grout that pumps into, and must cooperate bridge to starch the pressure-bearing leak stopping can be successful; The fiber leak-stopping cement mortar can block up position clearly medium and small crack leakage; Respond well from situation about using, obtained certain effect, but because the cement strength that forms is too high; When it is higher than the stratum rock strength, bore the leak stopping cement plug and get out new well easily; Have new weak zone to occur, cause the drilling depth loss, influence the drilling well speed-raising.
The leakage of the system in Tahe Oilfield Permian system at present mainly contains following characteristics: the leakage stratum belongs to the volcanic rock fracture development, and bearing capacity is low, misses easily; Permian system buried depth is generally between 4700m～5700m, and finishing drilling is at 6200m even darker, and this section well cementation belongs to typical deep-well, ultra deep well is prone to the drop ply well cementation; In the cementing process, the hydrodynamic column pressure is big, is prone to press the leakage stratum.
Summary of the invention
The objective of the invention is to overcome the shortcoming of prior art, provide a kind of leak stopping ability strong, can adapt to complicated leakage stratum, down-hole, can satisfy the novel concrete slurry leakage-stop liquid of the plugging operations of Permian system loss horizon.
The object of the invention is realized through following technical scheme: novel concrete slurry leakage-stop liquid, and it comprises following component, and the weight ratio of each component is:

Described patching materials comprises following component, and the weight ratio of each component is:
Fiber 0.1～0.4,
Shell 0.5～2.5,
Sawdust 2～4,
Rubber powder 3～6,
Mica 1～5,
Vermiculite 1～5.
Described staple length is 5～19mm.
Described light-weight additive is flyash or floats pearl; Anti-migration agent is fiber powder and silicon oxide, and the weight ratio of fiber powder and silicon oxide is 1:3～5; Weighting agent is little silicon; Water retaining be in AMPS polymkeric substance, keto-aldehyde condensation class and the PVA system any one or multiple; Retardant is the AMPS polymkeric substance, and said skimmer is a polyethers.
Said anti-migration agent is the powder that fiber powder and silicon oxide grind to form.
Described shell be in thin shell, in the thick shell, extraordinarily thick shell any one or multiple; Thin shell particle size range is 355～800 μ m in described, described in thick shell particle size range be 830～1600 μ m, described extraordinarily thick shell particle size range is 1700～3350 μ m.
Described sawdust is middle thin sawdust, and the particle size range of described middle thin sawdust is 400～2200 μ m.
Described rubber powder be in thin rubber powder and the extraordinarily thick rubber powder one or both, described in the particle diameter of thin rubber powder be 180 ~ 425 μ m, the particle diameter of described extraordinarily thick rubber powder is more than the 425 μ m.
The present invention has the following advantages: the present invention uses for reference through a large amount of theoretical investigationes and experience; Grain size and proportioning through the adjustment patching materials; Develop the patching materials that satisfies the leak stopping requirement; The present invention is directed to different cracks size and have stronger leak stopping bearing capacity, it is stronger to compare this leakage-stop liquid leak stopping ability of fiber leak-stopping cement mortar, more can adapt to complicated leakage stratum, down-hole; The present invention not only has good leak stopping ability, and the cement strength after solidifying is lower, prevents that leakage-stop liquid from solidifying the back and boring difficult " new well " problem that causes of plug; Can satisfy the plugging operations of Permian system loss horizon through a large amount of these grout leakage-stop liquids of indoor plugging effect evaluations proof, the intact back of plugging operations does not produce other disadvantageous effect to continuing to creep into simultaneously; The present invention is consistent with conventional grout leak stopping and fibrous cement paste plugging operations mode, need not complicated construction technology and parameter, the site work simple possible.
Further specify effect of the present invention below in conjunction with experiment:
The present invention is on the basis of analyzing existing leakage stopping technology; " stress cage " effect of using for reference in Xue Fulong Karen Phillips company " well reinforcement " theory is the research basis; Form patching materials through the collocation of a large amount of indoor material type selectings, material, and a large amount of leak stopping ability of research evaluation patching materials in grout, the mechanical property and the workability of grout leakage-stop liquid.
Patching materials in the novel concrete slurry leakage-stop liquid is the basis with the plugging fiber of different size, is aided with other leak stopping particle, can satisfy the shutoff on Permian system leakage stratum.The low density leak-stopping cement mortar that is the basis with this patching materials pumps into the down-hole after ground is mixed; Replace again to missing the stratum; Patching materials under the certain pressure effect in the grout gets into the anti-fluid in slit, stratum and gets into, and grout is frozen into solid-state formation cement plug and the shutoff stratum behind certain curing time.The cement plug that forms is different with conventional fibre leak stopping cement plug; It is higher that the fiber leak-stopping cement mortar solidifies the back cement strength; And the intensity of this novel concrete slurry leakage-stop liquid after solidifying is far below the fiber water mudstone; Its 24 hours ultimate compression strength are convenient to the appearance that follow-up brill plug prevents new well between 7～10MPa.
Novel concrete slurry leakage-stop liquid reaches the leak stopping purpose through " the part leakage-stop liquid gets into drop ply and solidifies gluing "; The well of weak zone in the drilling process is strengthened and reinforced; Prevent loss horizon follow-up creep into or the running casing process in miss once more, can play the effect on permanent mounting leakage stratum.The glued patching materials of small-particle is arranged in the novel concrete slurry leakage-stop liquid,, use novel concrete slurry leakage-stop liquid still effective, can effectively improve the stratum bearing capacity " well that do not miss in creeping into, bearing capacity is not enough ".
